ppc/xics: assign of the CPU 'intc' pointer under the core

The 'intc' pointer of the CPU references the interrupt presenter in
the XICS interrupt mode. When the XIVE interrupt mode is available and
activated, the machine will need to reassign this pointer to reflect
the change.

Moving this assignment under the realize routine of the CPU will ease
the process when the interrupt mode is toggled.
